I was having trouble with my 2004 RAM’s ECM, and this replacement unit worked perfectly. The fact that it arrived already VIN programmed saved me a ton of hassle—installation was basically plug-and-play. Shipping was surprisingly quick and affordable, which was a relief since I needed it urgently to get back on the road. The whole process was smooth, and the truck runs better than it has in months. I also appreciated how the seller promptly answered my questions when I called. Highly recommend!

Overall, a smooth experience that I’d recommend to anyone needing a programmed ECM for their 2004 Ram.
